can someone help me i have a kia sedona common rail diesel 2.9 2002 model the engine turns over and has plenty of fuel going to the fuel injectors but the injectors dont have any power (volts) going to them .i have tested the power leads and when the engine is turned over there is no voltage going to them . i have checked all the fuses and they are all ok . and all connections are ok so iam confused as i have enough mechanical knolage to fix it but its got me buged?

Oh you must be in Canada or overseas? We don't get this vehicle in the US, so I don't have a database on it.

Generally, on modern diesel the injectors are controlled electronically by a direct injection module. I think the only way to diagnose this is with a scan tool.

So can you momentarily start the engine with a squirt of starting fluid? --use very sparingly on a diesel---I'm only asking so that you can double-check your original diagnosis--it should kick right off with starter fluid.

I need some advice.I have a 1989 timberjack logging skidder with a 4 cyl.cummins motor.The motor runs good and will pull a heavy load, wide open but when you let off the gas it smokes bad !! The smoke is whiteish with a strong smell of oil,but does not use any oil,and when it idles after it is hot the motor will start to miss a little.Could it be the turbo,or the head or maybe the rings.And how can I test it to see which.I would be grateful for any help.

Truck is building pressure in radiator and pushing coolant into overflow jug, then out of jug on ground. I replaced thermostat and radiator cap, still have same problem. The factory temp guage has never showed hot. Any suggestions ???????????????

Gauge could be wrong. You might want to get a radiator thermometer to double-check. One thing that drives people nuts with diagnosing overheating issues is making assumptions, such as relying on the gauge, or thinking that because a part came new out of the box, then it must be good.

If in fact you aren't overheating, then you might have a clogged radiator. Have you ever put a stop-leak product in it? That'll do it.

Appreciate the advice, but since then it has began smoking white smoke out of the right exhaust tailpipe. I drive a big truck for a living and when they do this, it usually a blown head gasket. Of course it still has pressure in the radiator. I'm 99% sure it has not been hot. I checked the water temperature with a laser, and it shows around 190 degrees. What do you think about the head gasket "assumption" ?
